description, the fluid will be assumed to be Willkfl.

Tho lmily mmnbcr is enlarged between in ends in acmmnuxlale without restriction of llow, an inner statinnary shell 13, which only he termed thr, seat nie-mber. The burly member All which is preferably an iron 01 steel casting as all or part 0 the sheli 13 casi. inbcgral with it, to which it is connect- E- i by radial ribs 14. In this instance the scat, member 13 is composed of a main 1'- tinn facing the inlc'u end and connecm to the body member ll) by the ribs, and cast integral therewith as before stated, and a sir 'isrutcly formcd portion cmnposed of a stccl late 13 and a. cast, metal tip 13". As licfnrv rlfllfill, the seat member or shell may be cast in one intcgml piece, and it. is nnule hollow simply for the sake of lightness. It is shaped with tapered or conical forward and 1 war ends so as to erniit a sinonth flow of water whrn the va Va is open, it being understood that, the water coming from. the inlet end is divided by the ta-pergd nose of the "valve and flows around the same between 1119 radial ribs 1-1 and out; through the outlet end of the body. In this instance the inlet; and outlet; ends of the body are of the same diameter, and the construction is Such that. the capacity at the largest part; of the body member 10 is as great, and possibly sli htly greater than at either end.

n the inncr shell 13 is a seat ring .15, which may he simply a machinsd surface, or :1 scparuhring Such as a bronze ring set inlo :1 machined groove of the shell.

Tim riiw islnut, only serve to sustain the conlrul slivll 13, but they are extended axially imvurll what may be harmed the neck of th \ZilVL, the inncr smfuccs of the B-Xtfil'ltlml porlic-ns of the film lming horizontal or lJiLlllllPl ith thc axis and being prefm'ably hm-ll with brass or bronze lincrs l4 constituting lmzillllg surfaces for the valve pro in \vhrn in rloscil position and when it is ing iuoiml to and from closed position.

'l'ho valve member ll is rigidly secured by bolts or equivalent means 16 to the iuljw mint. Pil i oi the body member 10, and the ll-(Hiy nmmher l2 which for the most, part is conccnlric with respect, to. and is inside the nmnilmll, is bolted to the latter by bolts or rquivalcnt means 17 passing through ext rnnl flanges of the two parts. The two hmly members 1] and 12 are spaced apart,

ply by tnrnin open position. To insure this balanced'condition, the drain 34 should be closed. The returning of the control valve to neutral position noted above, not necessarythough it woulrLbe desirable in the event? there is used an electrically operated remote control valve.

In Figs. Sand 5 is shown a valve which may be employed advantageously when the direction of flow through the valve body is the reverse of that for which the valve ,of Figs. 1 and 2 is best adapted. The design shown in Figs. 1 and 2 is most etl'eetivewhen the movable parts, i. e. the movable valve rino is on the u stream end of the valve body, and the va ve of Figs. 1 and 2 could be employed when the direction of flow is the reverse of that indicated in Fig. 1, simthe valve end for end, in which event t e movable parts would still be on the tip-stream end of the valve body. However, it is sometimes the case, particularly in large installations; that it is desired that the down-stream or outlet endof the valve body be smaller in diameter than the upstream end, and while it is possible to make the inlet or up-stream end of the valve of Figs. 1 and 2 larger than the out et or down-stream end, nevertheless it. would be cheaper to have the movable parts at the smaller end of the valve body, and therefore at the down-stream endm It is largely for that reason that thec'onstruction'shown in Figs. 3 and 5 is provided. The construction of Fig. 3 differs from that first described chiefly in the arran ement of the pressure chambers by which t 1e valve ring is operated, the principle of operation bein the same. This valve has aninner seat mem er 36 connected to the body 37 of the valve by radial ribs 38 as in the first instance, but in thisv case the. enlar ed body portion of ;;the Valve hasan integra extension or neck 39,disposed axially in the direction of flow from the seat member and forming the outer wall of the annular space or chamber receiving the ring valve 40. The inner wall of this space is in this instance, for convenience of construction and assembly, composed of two members 4-1 and 42 which are secured together. i

It will be, observed that in this instance the main orbody portion of the valve ring to engages the outer wall or neck 39 of the valve body, and that the. end of the valve ring has a reduced part 40constituting the pision portion which divides the annular s; .re referred to into the two pressure chamhers 4 and 44-, which chambers are rererseiy arranged with respect to those of the construction first described, the arrangement being such that when the valve is closed, pressure may by leakage from the inlet side of the valve body enter the pressure chamber 43 and hold the valve closed, though pressure will not pass from V this chamber to the pressure chamber 44 for the reason that the reduced or piston portion 4U of the valve carries packing 45 which when the valve is closed, engages a shoulder lzi" of the member 4;. and this of feetively prevents pressure building up in chamber44.

The valve is controlled by tiuid pressii'ie through the medium of a supply pipe "46 which inthis instance (though not neee sai h ly) is connected to the body of the valvr. and by a fouruvay cock 4? and branch pipes 48 and -15) connected respectively to the two pressure chambers l3 and H. the connection of the latter chamber being zutcomplishod by a casting fit) in the \valeruvayor n'ecl; ol' the valve, though a pipe could be employed for this purpose.

When pressure is admitted to chamber 43 and exhausted from chamber 44, the valve is moved out of tbemouth or open end of the annular space receiving the. valve over into engagement with the valve seat, and in so doing, sliding over the liners of the ribs 38. It might be mentioned at this point that the,

reduced or piston portion 40 of the valve is engages the valve body member 41, and the valve body member 42 is preferably pro vided with a liner 32 over which the valve slides.

When the valve is in-full closed position the control valve 47 maybe moved to neutral position since pressure is maintained in chamber 43 by leakffige from/the inlet side of the valve body.

To open the valve, pressure is admitted to the chamber 44 and exhausted from 43, after which the control valve may be moved to neutral position, pressure being then built up by leakage in both chambers which maintains a balanced condition.

The valve of Figs. 1 and 2, or of Fig. 3' may be placed horizontally, vertically, or at any angle, regardless of the position, the operation being the same as that already described, though when the valve of Fig; 3 is arranged vertically, and the direction of flow is downward, the control valve is preferably not returned to neutral when the valve is closed.

Having described my invention, I claim:

1. A valve comprising a. valve body or casing having a centrally disposed stationary seat member around which fluidimay flowwhen the valve is open, said member having an outer valve seating portion a valve ring concentric with the valve body axis, said valve ring being positioned at one side of the valve seating portion of the stationary member and movable lengthwise of the latter into and out of engagement with the seat member, a chamber receiving said valve ring and formed by said ring into oppositely acting pressure chambers.

2. A valve comprising a valve body having an enlarged portion, a stationary seat member located within the enlarged portion and connected to the latter so that when the valve is open fluid may flow around the seat member, said member having an outer valve seating portion a valve ring carried by a portion of the valve body and positioned at one side of the valve seatin portion of the stationary member, said he y having bear: ing surfaces over which the ring slides in moving toward and from the seat membersaid valve ring forming in said portion of the valve body opposed pressure chambers.

3. A valve comprising a valve body, a seat member located centrally in a portion of the valve body, ribs connecting the valve body to the seat member forming passe es around the seat member, and a movable va ve member in the form of a ring centrally disposed with respect to the axis of the valve body axially of the seat member, means receiving said ring, and means for causing the ring to be moved toward and from the said member com rising opposed pressure chambers formed y said ring in the ring receiving means, said ribs having portions forming bearings for the'valve ring.

4. A valve comprising a valve body with a centrally disposed stationar seat member and said bod having axia y of the seat member a hollow portion closed at one end and havinga restricted annular opening at its opposite end, and a valve ring therein open,

fitting in an enlarged portion within the hollow ortion forming diiierentiali pressure chambers for the admission and exhaust of fluid to shift the ring toward and from the se member.

5. valve comprising aya-lve body with an i mer stationary seat member around which fluid may flow when .the valve is and said body having axially of the seat member inner and outer walls forming an annular space concentric with the axis of the valve body and open toward the seat member, a valve ring in said annular space forming two chambers to which fluid may be supplied or from which it may be exhausted to cause the valve ring to be moved toward and from the seat member.

6. In a valve, a valve body having an enlarged portion, containing an inner seat member with spacing ribs between the seat member and body, and said body having an annular chamber open toward the seat memher, an annular movable valve in said chamher having a portion adapted. to slide over said ribs into and out of engagement with theseat member and having a portion in said chamber constituting a iston dividing the chamber into separate dhid receiving portions.

In testimony whereof, I hereunto afiix my signature.

the restricted opening and having DONALD WI. SLATTERY.
